CHT-LDOP
CHT-LDOP is Low-Dropout Voltage Regulator manufactured by CISSOID.
Description
The CHT-LDOP is a 1A, low-dropout linear voltage regulator patible with hightemperature environments. Typical operation temperature range extends from -50°C to 225°C. The circuit is stable throughout the whole temperature range and under a large choice of capacitive loads. The minimum dropout voltage (Vin-Vout) is 2V with a 1A load current at 225°C and 1V for load currents lower than 400m A. The dropout voltage can span from 1 Volts to 20 Volts(1). The circuit is a one-die solution. CHT-LDOP is available in TO-254 package and in bare die.
